The Reformed Teaching Observation Protocol (RTOP) was developed as an observation instrument to provide a standardized means for detecting the degree to which K-20 classroom instruction in mathematics or science is reformed.  RTOP consists of 25 items, each using a 5-point Likert scale.  These 25 items are divided equally into 5 categories: Lesson Design and Implementation, Content: Propositional Pedagogic Knowledge, Content: Procedural Pedagogic Knowledge, Classroom Culture: Communicative Interactions, and Classroom Culture: Student/teacher Relationships.

The Science Teaching Efficacy Belief Instrument (STEBI) is used in many studies to measure science teaching self-efficacy and outcome expectancy in preservice elementary teachers.  This 25-item instrument uses a 5-point Likert scale.  

The STEBI-A is the version recommended for use with in-service teachers; the STEBI-B is the version recommended for use with pre-service teachers.

The STEM Semantics Survey measures student interest in science, technology, engineering and mathematics as well as interest in STEM careers. The survey is comprised of five scales each with five items measured on a 7-point scale. The STEM Semantic Survey is appropriate for administration to middle school students and teachers.
